On the noon of the 23rd, the closing ceremony of the 2025 World Gas Congress was held at the Beijing National Convention Center, marking the successful conclusion of the 29th World Gas Congress. During the conference, the Chinese team of the organizer and the leadership of the International Gas Union (IGU) jointly participated and closely cooperated, dedicating a rich and fruitful event to the global gas industry. The closing ceremony kicked off in a lively atmosphere, and a wonderful cultural performance presented cultural congratulations to the conference. The dancers performed a dance called "Wing Chun" that incorporated Southern Fist techniques, followed by the melodious song "Time to say goodbye" echoing throughout the venue, showcasing the beautiful integration and innovative expression of Chinese and Italian cultures, winning rounds of applause from the audience. The conference summary video reviewed the wonderful moments of the four-day conference, evoking fond memories of the conference time for the attending delegates.

In modern industrial systems, nitric oxide (NO) plays a dual role - driving advancements in chemical, pharmaceutical, and other industries while posing significant safety risks. This article provides an in-depth analysis of NO's properties, hazards, and response strategies.

As the flood season approaches, there are often heavy rain and strong wind weather, and situations such as waterlogging and floods also occur from time to time. In the face of heavy rain, how can we prevent gas detectors from getting waterlogged? Can the instrument still work properly after getting waterlogged?

There are many reasons why gas detectors frequently alarm, mainly including the detection of abnormal gas concentrations, changes in the surrounding environment, and problems with the device itself. The following are some common factors that cause abnormal gas detector alarms.

In the complex landscape of industrial production and urban environments, nitrogen dioxide NO2 is a gas that demands our close attention. It is not only a common by-product of various industrial processes but also a significant contributor to air pollution, posing threats to both human health and the environment. This article will comprehensively explore the nature, hazards, and preventive measures related to nitrogen dioxide.

In order to ensure safe production, gas detectors are widely used in various industries. Gas detectors can monitor the leakage concentration of toxic and harmful gases and flammable gases in the air in real time, effectively preventing the occurrence of various accidents such as fires, explosions and poisonings. When using gas detectors in daily life, users will find that the detection range on the instrument label often shows similar figures such as 0 - 100LEL% or 0 - 2000PPM. Or on the LCD screen of the gas detector, VOL% or PPM may also appear. What do these three units specifically mean and how do they convert among each other?

Today, we will continue to introduce another common gas-ammonia.

01. What is IP protection?

Gas detectors are widely used in fields such as petroleum, chemical, metallurgical, and catering, effectively preventing the occurrence of hazardous accidents such as fires, explosions, poisoning, and suffocation, and ensuring production and life safety. So, when did people start to realize the dangers of gases? How were gas detectors developed for gas detection?

A flammable acidic gas, colorless, can form an explosive mixture when mixed with air, and can cause combustion and explosion when exposed to open flames and high heat energy. At low concentrations, there is a foul egg odor, and at extremely low concentrations, there is a sulfur odor, which is highly toxic.
